Gene m1 description.

'llhis invention is shown embodied in a cash register of the type shown and described in the patent to Frederick L. Fuller No. 1,394,256. In machines of this type 1t is usually customary to provide three banks of control keys. Such machines can also be equipped with any number of cash drawers from one to nine, one drawer being provided for every three clerks using the machine. In previous machines of this type the release of the cash drawer was controlled by a single bank of keys, but this machine has been designedso that each cash drawer may be re'eased by a key in each of the three control banks. It willbe evident from the following description of the invention that the construction shown herein is of a flexible nature, andit is not intended to confine the invention to the particular form shown herein, nor its use to the particular type of cash register disclosed.

Key board and differential mechanism.

The three banks of control keys, which are all of the keyboard with which the present invention is concerned are identically the same, and may represent twenty seven clerks having access to nine cash drawers, with the corresponding key in each of the three banks controlling the opening of one cash drawer. The mechanism in general for these three control banks of keys is similar to that shown in detail and described in the above mentioned Fuller patent, with this exception, that the interlocking mechanism necessary in the Fuller patent which compels the depressing of one key in each of the three controlbanks before the machine can be operated, is omitted in this invention. The description, thereof,in this application will therefore be as much simplified as possible. For the sake of convenience, the control banks will be referred to by number herein, for exampe, as banks 1, 2 and 3, from right to left. Each bank contains nine keys (Fig. 1), which are slidably mounted in a key frame 31 supported at its upper and lower ends by rods 32 and These keys are adapted to be held in their depressed position during the operation of the machine, and restored to their undepressed position at the end of such operation in a manner which is very well known and the description of which is accordingly omitted here.

The differential mechanism for the re lease banks is also old and well known and only a brief description thereof will be included in this application. A latch member 34; is pivotally supported by an arm 35 and a bell crank 36, which are in turn car ried by a differentially movable member 37. This member is pivoted on a stud 38 and is driven by an invariably moved segment 39, also pivoted on the stud. The segment 39, as is well known, is given its invariable movement by means of a link 4E0, a Y-shaped member 41 and a pair of cams 42 and 43 which are fast on a shaft 44. This shaft is the main drive shaft of the machine and receives one complete rotation on every item ciiteri op ration thereo", thereby cansii'ig the 1 to rock nrst clockinner end of whichever one ot the is been deprcs i. ll hen "his latch nieniber Si \vi l be discon .1011] St 110ml (1 (m1 uni lnlclliiluly segment 39, sad the diti'erintially member 3? will be stopped in a 'orrespondinc; to the lacy depressed. ev in a bar it has been depressed the be l; rol:en by means ot a zero stop in the path of a member 4; n nroiien aw pivoted on the stud 23'. and connected to t a bell crank lever 30 by a slot and pin cone. 1 The operation of this in cl Lnisni fl and very welllillOTfll. and i oi d tion for lio.

The arm 53 appropriate to the third control bank has secured thereto a segment gear the teeth of which mesh with teeth 56 formed on the torward end or a rack the forward end of which slidablv nion: ictl on a crc member 58, ie rear end being supported by the machine 7 rue. T he rear end of the rack 57 carries teeth 59. which mesh with a gear loosely mounted on a shaft 61 supported by two:

brackets 62 and 63 (Fig. 3) supported on the base of the machine.

The links 51, which correspond to the first and. second banlts of control keys, are piv- 0 ill; connected to arms (Bl and 65, respectively, (Fig. 2) to which are secured segrent rears (6 and GT. The segment gear (56, appropriate to the first control bank, 1 shes with teeth 68 formed on theffiorward 03' a rack 69. The segment gear 67, ropriate to tie second control bank, res with teeth formed on a rack 70. of the racks 69 and 70 are slidably l L iesired totalizer in a manner which is mounted at their forward ends on the cross member 58 and at their rear ends slide on the base of the machine (Figs, 2 and 3). The rack (39 has a plate 71 secured thereto, which carries teeth meshing with a pinion 72 fast on a short shaft 73, the ends of wnich extend through slots Tet torincd the machine. The arm 77 carries teeth 78 on its upper edge meshing with a plnion 79 secured to the shatt {31,

As this gear is loose on the shaft ll, however, it is evident th it di'l'lercntial iuoi'eineut iinparted o this air will have no effect on the shaft (ll.

If, however, the key depressed is in either the first or second control bankr, then the differential movement will, through the parts above mentioned, be given to either the rack (39, or the 'aclz 70. As shown in Fig. 2, the rack 69 is in its 9 position, and therack T0 is in its 07 position. It, on the nextoperation of the machine, the 9 key in the second control bank is depressed, the rack 69 will be returned to its 0 position, and the rack wil be moved to its 9 position. It can be seentl at as, the lliOVGlllGlii' of these two aclcs, in this particular instance, is the same. only in opposite directions, and the plates Tl.

and '75 cooperate with opposite sides of the pinions 72 and 76, there will be no relative lllOYelIlDloi the arm 77 on this operation, and therefore the shaft (Bl will not be rotated. When a he in the third traisaction bank is depressed, then the 'ack 69 will simply return to its 0* position, in which position the plates 71 and 75 are directly opposite, with the pinions'TQ and 76 in approxiinately th, center oi said racks. It can be seen that as the rack 9 returns to O, the rack 70, being held motionless, the pinions 76 will simply roll over the teeth on the plate 75 and the arin'z'i' will be carried rearwardly. The teeth onthe arm 77 will thereupon rotate the pinion 79 fast on shaft 61 and rotate this shaft to its O position. It can beseeni that, due to the above construction the inions 72 and 76 are rotated the difference between the movement of the racks G9 and 70, and this movement will therefore,

Looselv it v) through the arm 77 and pinion 79, rotate the'shaft 61 differentially, in accordance with the key depressed in either of the first or second control banks.

Drawer mechanism.

. The drawer mechanism of the present machine is. of conventional design in most respects, and it is not believed that a specific description of the mechanism is essential to an understanding of the invention. The machine contemplated by the present invention is provided with nine cash drawers, only the upper two of which are shown in Fig. 3. Each of the cash drawers is slidably mounted in an opening in the base of the machine. On the back of each of the cash drawers a bracket 91 is bolted, to which is pivoted a drawer latch 92 (Fig. 1.), having a shoulder 93 engaging a hardened plate laid in a. bar 94 extending laterally across the rear of the machine and supported by vertically extending members 95. There is one of these bars 94 for each drawer. The latch 92 is held in its latching position by a spring 96 stretched. between a projection on the latch 92 and a pin on the bracket 91. \Vhen the drawer is unlatched, in a manner which will presently be described, it is moved forwardly out of the drawer cabinet under the influence of two springs 97, the construction and function of which are old and well known.

The cash drawer to be released is selected by the key depressed in any of the three control banks. If the key depressed is in the third control bank the gear 60 will be rotated differentially in accordance therewith. This gear is connected by means of clutch member 98 (Fig. 3) with a spiral gear 99 loose on the shaft 61. This spiral gear meshes with a spiral pinion 100 (Figs. 1 and 4) fasten a short vertical shaft 101. At its lower end, the shaft 101 carries a member 102, the front and back of whicl'rare flattened, and which is adapted tobeinserted into a corresponding opening in a cylindri cal member 103 carried on the upper end of a shaft 104. It can be seen from Fig. 4 that due to the construction of these parts a rotary movement of the spiral pinion 100 will be transferred to the shaft 104, and also a vertical movement of the shaft 104 and the member 103 can be effected Without raising the spiral pinion 100.

Fast on the shaft 104 are a plurality of lugs, or fingers, 105 which are differentially and spirally disposed about the periphery of the shaft, one opposite each of the cash drawers. Thus, if the 9 key, in the third control bank, is depressed and through the differential mechanism the shaft 104 is rotated to its 9 position, the lug 105, appropriate to the lowermost, .or ninth, cash drawer will be moved into position to coopcrate with this drawer. Pivotally mounted on the frame 94, for each drawer, is a lever 106, the movement of which is limited by a pin 107 which projects through an opening in said lever. This lever extends laterally of the machine and normally lies just above the latching arm 92 for its appropriate cash drawer. It is evident that when the right hand end of the lever 106 is raised, the left hand end will be lowered, and therefore the latch arm 92 will be pushed downwardly far enough to disengage its shoulder 93 from the plate in bar 94, and thereby permit the springs 97 to force the drawer forwardly to its open position.

Parallel to the shaft 104 is a shaft 108, which carries fingers 109 in exactly the same relation as the fingers 105 previously de scribed. At its upper end, the shaft 108 carries identically the same mechanism that previously described in connection with the shaft 104, and it is therefore thought to be unnecessary to describe this mecha nism again at this point. It is thought to be sufficient to say that the shaft 108 receives its movement through a spiral pinion 110 (Figs. 3 and 4) which cooperates with a spiral gear 111 fast on the right hand end of the shaft 61. It will be remembered that the shaft 61 is rotated differentially through the pinion 79 and arm 77, driven by either the rack 69 or the rack 70, depending upon whether the control key was depressed in the first, or second, banks. In other words, when a key is depressed in the first, or second, banks, the shaft 108 will be differentially rotated inv order to bring the appropriate finger 109 into position to release the cash drawer appropriate to the key depressed, while if a key in the third control bank is depressed, the shaft 104 will be rofated to accomplish the same function.

Means for trapping the (5')(612067 latch.

No matter which of the shafts 104 or 108 is selected to release the cash drawer they will. both be operated in order to release the desired drawer. It can be seen from Fig. 4 that the member 103 and its corresponding member on the shaft 108 both have a horizontally extending channel 112 cut therein. Fast on a shaft 113, adjacent each of the shafts 108 and 104, is a U- shaped member 114 which carries two pins 115 projecting into the channel 112. Fast on the shaft 113 is an arm 116, the free end of which rests on the left hand end of a lever 117 pivoted on a stud 118 of the frame. The opposite end of the lever 117 carries a roller 119 which cooperates with the periphcry of a cam 120 fast on a shaft 121. This shaft is the main printer drive shaft shown in the above mentioned patent and receives a complete clockwise rotation (Fig. 4) upon every operation of the machine. lVhen this &

rotation takes place the cam 120 will rock the lever 11? clockwise, which will-in turn rock the arm 110, shaft 113 and U-shapedinembers lllalso clockwise, thereby raising the member 103 and its counterpart on shaft 108 together with shafts 10 1 and 108 upwardly. The cam 120 willthen permit the parts to return to their normal position, as shown in Fig. 1. Upon the upward moven'ient ot' the shafts 104- and 108 the lug 105, or

the lug 109, depending upon in which bank of control keysa key was depressed, will cooperate with a downwardly extending projection 122, or 1L3, carried by an arm 121, and will rock this arm clockwise. The arm 1211', at its left hand end, h'as abent portion lying just beneath the righthand end of the lever 106 appropriate toeaeh drawer, and therefore, it this arm 1% is rocked by the lug on either otthe shafts 104C or 108, it is evident that the lever 106 will be rocked counterclockwise, thereby disengaging; the latch 92- and releasing the particular cash drawer selected.

li hile the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to contine the invention to the one form of embodiment herein disclosed, for it is susceptible of embodiment in various forms; all coming within the scope of the claims which follow.
